The N.C. Youth Risk Behavior Survey (N.C. YRBS) provides a critical source of public health data for understanding the scope of injury-related
problems and measuring progress toward overall goals among public school students. N.C. YRBS is a comprehensive statewide
sample of 2,000 middle and 2,300 high school students from across the state. Every other spring in odd years, a core set of injury-related
questions are asked along with other health and risk-factor questions. Risk-factor variables include information such as alcohol use, seat
belt use and physical assault. The sampling scheme is intended to generate a statewide representative sample of weighted data. Increasing
school district participation and data utilization are two keys for future success. See the N.C. Healthy Schools website for more
information: www.nchealthyschools.org.
Weighted to provide estimates representative of the public high school student population; students who reported having driven a car or other
vehicle one or more times during the past 30 days when they had been been tedrinking alcohol. Specific data on 95 percent confidence intervals
and regional definitions is at the N.C. YRBS website: www.nchealthyschools.org/data/yrbs.
*NH = Non-Hispanic. **Caution when interpreting. Results based on small sample size.
